Best way to fight the cold!!!

I heard this from another guy and actually tried it myself, and it works really well. I surf in San Diego. The water temp right now is like 56 degrees I think. I have a 3-2 wetsuit with 3-2 booties. I was starting to get really cold. Then I started filling up a gatorade bottle with hot water and taking it to the beach with me. Right before I get in the water, I pour the warm water into my wetsuit. It keeps me really warm because it prevents that first bit of cold water from coming in. Give it a try.
